SPRING SHOCK-ABSORBER.

Application filed .Tune 9, 1917.

To all .Ir/mm e' Imay x0/teem.;

a citizen ot' the llnited States, residingat..

sorhers. of which the following is a full,v clear, concise, and. exact description. reifer-- ence being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in spring shock absorbers.

One object of the invention is to provide a spring plate shock ahsorher, more, particularly adapted for draft gears, having' a greater capacity for the space occupied than spring shock alfisorhers heretofore used.

Another and more specific object ot the invention is to provide a corrugated spring` plate shock' ahsorher so formed and arranged that the spring` plates prevent a decrease of capacity as the ultimate load is applied.

In the drawing 'forming ay part ot this specification, Figure l is a horizontal sectional view of a portion ot' a ailway d at't rigging' showing' .my improveinents| as applied thereto. Fig. Q lis a transverse vertical sectional view, taken suhstantiallv on .line 242 of Fig. 1. And Fig. fl is a per-- speetive view of two ot' the, spring;- plates employed with my imprewenients.

lfn said drawing. 10--10 denote channel center sills of a railway car 'to which are secured rear stops 11 and front stops 1Q'. A. draw bar 13 having a yoke 14 also shown. the improved shock alisorher being mounted within the' yoke ant eoiperahle with the, stops.

As shown. the spring shock ahsorl-)er is comprised of a series of spring plates A-A havingr an alternate series of, spring plates B--R interposed therebetween. Two end 4Followers Cw@ are also employed, saidL followers when employed with a draft rigging' cooperatingwith the stops 1l and l2. As shown. each of the. followers C is provided on its inner tace with a series of corrugations 1li-1liwhich corrugations are ot shorter radii than the Corrugations 15-15 formed ,in the adjacent spring plates A and in this connection, it will he understood` that all of the, spring plates A are of similar construction. Each of the, springplates B is also corrugated. as indicated at 1li-16,the`

lowers and in the plates .i and l heine rrangred in parallel. as shown in the drawing. As clearly appears i'roni Fig. l. the end spring; plates` A engage the high points ol .the ctnrugalions it on the inner faeesoi" the followers and are spaced from the low or depressed portions ot' the eoirugations ot' the followers t. The eorrueations ot the. plates lh heine` oi" shorter radii and thereA fore et greater amplitude. will engage the plates it on one side in the low or depressed portions of the corrugations l5 thereot. and, willr engage the plates A on the opposite sides thereof at intermediate points ol the, -is rlearly shown in Fig. l. the plates .t are normally of .g'reater over-ail length than the normal ov all length of the plates. B.

in operation, upon relative approach ot the followers C. it is apparent that the plates B will tend Yto tlatten ont, and in so doiner will slide and thus create. trhthui on the plates'A'. The latter in turn will tend to no corrugated (ileeper than normal and will thereby contract. in oveiwall length, said plates A' tei'idinp; to eontorin to the corrugations on the inner fares of the folhiwers With thsa-rran ement it is ohvions that. as

of corrugated spring plates and which re-v snltsin a loss of Capacity at the ultimato load. If`l1rtliei'1nore, the friction crea ted with, my arrangement adds materially to thel eapaeity of the shock absorber, and inasmuch as the` engaging frietion surfaces are well distributed over av large area, the wea will be materially reduced With the a-m'angeinent above described, the shook absorber 1s of high capacit-y; does not lose capaeity'as the ultimate load is applied; and for equal space occupied, is of greater capacity than the ordinary spring plate shock absorbers.

lt will also he noted that on account of the eorrugrations being arranged 1n parallel,

there is no tendency for the plates to slip or..

work sidewise and thus ont of position.

l claim:

1. In a spring shock absorber, a plurality of spring plates, said plates being eorrnrgated, the eorrugations of seine platea heini;

of greater amplitude than eorrugations of the other plates.

2. In a spring shock absorber, a plurality of spring plates, all of said plates being corrugated and alternate plates havingthe corrugati'ons thereof ofshorter radii' than the others. I i

3. In a spring'shock absorber,.a plurality of spring plates, said plates gated, the corruga'tions of some plates being of greaterV amplitude than `corrugetions of the other plates, and all of said corrugations being arranged in parallel.`

In ya sprmg shock absorber, the combi-- nation with a pair of followers having their inner faces corrugated, of a plurality kof vspring plates interposed between said followers Aand having` also corrugetions, the radii of the corrugations of some of seid plates differing from the radii of others of said pla-tes. l

5. In a spring shock absorber, the eombibemg corru-. v

nation with a pair of rela-tively movable followers having corrugated inner faces, of a series of coz-ru ated spring plates interposed between saidollowers, the eorrugations of said plates being of dierentradii and so arranged that, as the followers approach each other, some plates will tend` to Hatten 'out fend others become more deeply corrugated.

6, In a Shockabsrber, the' combination with two series of spring plates, both series belng Corrugated `withthe corrugations extendmg parallel, the corrugations of one series belng deeper than the co'rrugations of the other series whereby upon compression, the corrugations of the spring plates having the deeper corrugations will tend to flatten out andthe. corrugations of 'the remaining spring plates tendlto beeolne deeper.

In Wltness that I clairn the foregoing I have hereunto 'subscribed day of May, 1917.
